TECHNICAL FIELD

The present disclosure relates generally to a supporting system or structure, and more specifically, to a system or structure for supporting a patient or an object used in an examination system.

BACKGROUND

Modern medical diagnostics generally relates to support an object or a patient under examination on a supporting device such as a table or a bed and to scan and diagnose the object or the patient in a corresponding apparatus. Typically, the apparatus and the supporting device are specially designed for and used in a particular medical diagnosis system. For instance, an X-ray computerized tomography (hereinafter referred to as CT) bed can only be used together with a CT scanner to perform a CT scan.

A plurality of medical examination techniques may be used either individually or concurrently in a diagnosis. A patient may need to either walk to or be moved between different examination devices to undergo different examinations. After the patient is moved from a first examination using a first examination device to a second examination using a second examination device, the patient may need to be readjusted to a desired posture before the second examination may be performed. Due to the move, the readjustment may be needed even if the desired posture in the first examination is the same or similar to the desired posture in the second examination.

In some examinations, a patient may need to maintain a specific posture for an examination to be properly performed. An examination performed when the patient fails to maintain a satisfactory body posture may introduce artifacts. Moreover, repeated adjustments of the posture of the patient and/or repeated attempts to perform the examination may increase not only time and costs, but also exposure to one or more agents used in the examination. For instance, if a radiation based imaging examination is involved, repeated attempts to perform the examination may increase the radiation exposure to the patient.

There is a need for a supporting system for supporting the person undergoing a plurality of examinations using a plurality of examination devices. There is also a need for a support device for helping a patient to maintain a desired posture in one or more examinations.

Then images of the region of interest of the patient or the object may be generated by the signal from the detector.

FIG. 7 to FIG. 9 illustrate exemplary multi-modality diagnostic imaging systems using the supporting system disclosed herein that the table is fixed connected to the first holder 1210 according to some embodiments of the present disclosure. As shown in FIG. 7 and FIG. 8 , when a CT scanning procedure is operated, the patient or the object may lie on the table 1100. The sliding device 1220, driven by the driving device, may move along the guide device 1300 along the length direction 180 and approach the imaging volume 2002. Then the table 1100 may enter the imaging volume 2002, and images of the region of interest of the patient or the object may be generated. After the CT scanning procedure completes, the sliding device 1220, driven by the driving device 13 (not shown in the figure), may move along the guide device 1300 along the length direction 180 of the table 1100, and depart the imaging volume 2002, causing the table 1100 to exit the imaging volume 2002.

After the CT scanning procedure completes, the patient or the object may further need angiography. As shown in FIG. 9 , at least a portion of the first holder 1210 may protrude outside of the support device 1200. At least a portion of the table 1100 may not overlap with the guide device 1300. In some embodiment, at least a portion of the first holder 1210 may extend along the width direction of the table 1100. In some embodiments, the projection of the region (or referred to as contact area) of the first holder 1210 that contacts, supports, or is connected to the table 1100 may partially overlap with the projection of the region (or referred to as contact area) of the first holder 1210 that contacts, or is supported by or connected to the sliding device 1220; one or both of the projections may be onto the ground or the plane where the guide device 1300 (described elsewhere in the present disclosure) is located. In some embodiments, the projection of the region (or referred to as contact area) of the first holder 1210 that contacts, supports, or is connected to the table 1100 does not overlap with the projection of the region (or referred to as contact area) of the first holder 1210 that contacts, or is supported by or connected to the sliding device 1220; one or both of the projections may be onto the ground or the plane where the guide device 1300 (described elsewhere in the present disclosure) is located. A space formed by the guide device 1300, the sliding device 1220, and the first holder 1210 may be used to accommodate the angiography device 30. When sequentially operating CT scanning and angiography, the patient or the object do not need to move from one table to the other one. The position of the patient or the object relative to the table may remain essentially the same between examinations. The position of the patient or the object on the table 1100 does not need to be adjusted for in a different examination system. In some embodiments, the sliding device 1220 may include an extendable structure that may extend or contract in the vertical direction 170, causing the table 1100 to move in the vertical direction such that the distance between the plane of the table 1100 and the guide device 1300 may be adjusted.

FIG. 10 to FIG. 11 illustrate exemplary supporting systems in multi-modality diagnostic imaging systems according to some embodiments of the present disclosure. The table 1100 may be slidably connected to the first holder 1210 according to some embodiments of the present disclosure.

When a CT scanning is performed, as shown in FIG. 10 , the center line of the guide device 1300 along the length direction of the table 1100 may align with the axis of the gantry in a same vertical plane. The sliding device 1220 moving along the length direction of the guide device 1300 and convey the table 1100 into the gantry for generating CT images of the region of interest of the patient or the object.

After the CT scanning procedure completes, as shown in FIG. 11 , the sliding device 1220 may move long the guide device 1300 and retract the table 1100 away from the gantry. Then the table 1100 may move along the width direction of the table 1100 and away from the sliding device 1220. The first holder 1210 may extend along the width direction of the table 1100. Thus when the table 1100 moves to the extension area, the projection of the region (or referred to as contact area) of the first holder 1210 that contacts, supports, or is connected to the table 1100 does not overlap with the projection of the region (or referred to as contact area) of the first holder 1210 that contacts, or is supported by or connected to the sliding device 1220; one or both of the projections may be onto the ground or the plane where the guide device 1300 (described elsewhere in the present disclosure) is located. Meanwhile, the table 1100 does not overlap with the guide device 1300. A space formed by the guide device 1300, the sliding device 1220, and the first holder 1210 may accommodate the angiography device 30. When the angiographer 30 operating angiography procedure, the C-shaped arm may occupy the space and be positioned close to the patient or the object for examination. The patient or the object may be placed between the emitter and the detector, while radiation emitted by the emitter may pass through the region of interest of the patient or the object and may be received by the detector.

FIG. 12 illustrates an exemplary multi-modality diagnostic imaging system according to some embodiments of the present disclosure. As shown in FIG. 12 , when CT scanning procedure is operated, the patient or the object may lie on the table 1100. The table 1100 may enter the imaging volume 2002 by changing position of the table 1100. The table 1100, driven by the driving device, may move along the second holder 1212. The table 1100, driven by the driving device 14, may rotate around the second holder 1212. Height of the table 1100 relative to the ground may be controllable by adjusting height of the sliding device 1220. Then the table 1100 may enter the imaging volume 2002, thus the imaging components placed in the gantry 2001 may generate images of the region of interest of the patient or the object.

After the CT scanning procedure completes, the table 1100, driven by the driving device, may be configured to move along the second holder 1212 and depart the imaging volume 2002, thus the table 1100 depart the imaging volume 2002. Then the table 1100, driven by the driving device 14, may rotate around the second holder and may align the center line of the table 1100 along the length direction in a same vertical plane with axis of C-arm of the angiographer. Then, the table 1100 may be configured to further move along the second holder 1212 to reach predetermined position relative to the C-arm.

FIGS. 13 a, 13 b , 14 and 15 illustrate a head supporting device to help the patient to easily and quickly adjust to a desired head posture and to maintain the posture during the examination.

Examples of such examinations that the head supporting device may be used in may include but not limit to a digital subtraction angiography (DSA) system, a Magnetic Resonance Imaging (MRI) system, a magnetic resonance angiography (MRA) system, a computed tomography (CT) system, a computed tomography angiography (CTA) system, an ultrasound scanning (US) system, a positron emission tomography (PET) system, a single-photon emission computerized tomography (SPECT) system, a CT-MR system, a CT-PET system, a CE-SPECT system, a DSA-MR system, a PET-MR system, a PET-US system, a SPECT-US system, a TMS (transcranial magnetic stimulation)-MR system, an US-CT system, an US-MR system, an X-ray-CT system, an X-ray-MR system, an X-ray-portal system, an X-ray-US system, a Video-CT system, a Vide-US system, or the like, or a combination thereof.

In some embodiments, the angles and the structure of the head supporting device may be designed so that once the patient places the head on the head supporting device, the head of the patient may be positioned to a desirable position in an examination of, for example, the head. In some embodiments, the head supporting device may include multiple surfaces with different angles and/or surface contours. In some embodiments, the head supporting device may be detachably assembled using a plurality of parts.

In some embodiments, the angles and the surface contours of the surfaces of the head supporting device may be configured so that when the patient lays his head on the head supporting device, a particular angle may be maintained between the geometric reference such as the vertical direction Z (as shown in FIG. 13 a and FIG. 13 b ) or the horizontal direction (that may be perpendicular to the vertical direction) and a referenced line or plane in body of the patient. In some embodiments, the angle may be configured and maintained in the examination to obtain a clearer image. In some embodiments, the angle may be configured and maintained in the examination to immobilize the patient for generating a more stable image. In some embodiments, the angle may be configured and maintained in the examination to reduce the artifacts wherein the artifacts may be caused by a scan in a section where human tissues overlap or by an unexpected movement of the human body. In some embodiments, the angle configured and maintained in the examination may relate to the comfortableness of patient or any other issues.

In some embodiments, the angles and the structures of the head supporting device may be configured so that when the patient lays his head on the head supporting device, the angle between the vertical direction Z (as shown in FIG. 13 a and FIG. 13 b ) and a reference line within the head of the patient such as an orbitomeatal line (hereinafter referred to as OML) or a canthomeatal line may be a constant. In some embodiments, the angle between the vertical and the OML may be a constant value as needed in a particular type of examination. In some embodiments, the angle between the vertical and the OML may be between 15 and 20 degrees. The head supporting device may be used in a radiation therapy such as X-ray, CT scan, MRI, etc.

FIG. 13 a and FIG. 13 b illustrate two configurations of a head supporting device used for a CT scan of the coronal section of a patient. As shown in FIG. 13 a and FIG. 13 b , the head supporting device may include a frame 2101 and a pad 2102. The frame 2101 may support the shoulders of the patient. The pad 2102 may support the head of the patient. The pad 2102 of the head supporting device may have a first configuration as illustrated in FIG. 13 a , and a second configuration as illustrated in FIG. 13 b . The frame 2101 may include a groove 2103 with a particular shape. The groove 2103 may be essentially flat (also referred to as the XY plane) on the frame 2101.

In some embodiments, the length of the pad 2102 may match at least the width or the length of the groove 2103 of the frame 2101 so that the frame 2101 and the pad 2102 may be connected. In some embodiments, the groove 2103 may be rectangular wherein its length is greater than the width, and the pad 2102 may be configured to match the width of the groove 2103 so that the pad 2102 may be connected or folded into the groove 2103. In some embodiments, the groove 2103 may be oval or circular, and the pad 2102 may be configured to match the length of the diameter (major axis if oval) of the groove 2103 so that the pad 2102 may be connected or folded into to the groove 2103.

In some embodiments, the pad 2102 may be fastened to the groove 2103 of the frame 2101 by a roller (not shown in the figure) through the pad 2102 in the width direction, as illustrated in FIG. 13 a and FIG. 13 b . In some embodiments, the surface of the pad 2102 and frame 2101 may be made of a friction material so that when the pad 2102 is folded into the groove 2103 of the frame 2101, the frictional force between them may be high enough to immobilize the pad 2102. In some embodiments, the pad 2102 may be of an elastic material including, for example, rubber, or the like. The pad 2102 may be compressed, folded into the groove 2103 and then expand within it, so that the pad 2102 may be immobilized or confined in the groove 2103. In some embodiments, the groove 2103 may be made of a first material and the pad 2102 may be made of a second material, wherein the first material and the second material may be sticking or attractive to each other. In some embodiments, the first material and the second material may be Velcro™ or magnetic materials, respectively.

The pad 2102, as shown in FIG. 13 a and FIG. 13 b , may include a first surface 2125, an undersurface 2126, a first side 2121, and a second side 2122. The first side 2121 may meet the first surface 2125 and the undersurface 2126. The second side 2122 may meet the first surface 2125 and the undersurface 2126. In some embodiments, the first side 2121 and the second side 2122 may be opposite to each other.

FIG. 13 a illustrates an exemplary head supporting device. The head supporting device may be used in, for example, a CT scan when the patient is prone. More specifically, the undersurface 2126 of pad 2102 may be connected to the groove 2103 so that the jaw of the patient may be supported by the first surface 2125 of the pad 2102. In some embodiments, the undersurface 2126 may directly contact the bottom surface 2131 of the groove 2103.

FIG. 13 b illustrates an exemplary head supporting device. The head supporting device may be used in, for example, a CT scan when the patient is supine. More specifically, the second side 2122 of the pad 2102 may be connected to the groove 2103 so that the patient's neck may be supported by the first side 2121 of the pad 2102 and the head of the patient may be supported by the undersurface 2126 of the pad 2102. In some embodiments, the second side 2122 of the pad 2102 may directly contact the bottom surface 2131 of the groove 2103. In some embodiments, the first side 2121 and the undersurface 2126 may be configured into a continuous and unitary surface to concurrently support patient's head and neck when the patient is supine (lying on the back).

In some embodiments, the angle between the second side 2122 and the undersurface 2126 may be chosen such that a desirable angle between the vertical direction and the OML of a patient may be achieved. For instance, if the desirable angle is between 15 degrees and 20 degrees, the angle between the second side 2122 and the undersurface 2126 may be between 70 and 75 degrees. To be illustrative, an intersection line may be formed by a plane perpendicular to a length direction of the groove 2103 intersecting the undersurface 2126 and another intersection line may be formed by a plane perpendicular to the length direction of the groove 2103 intersecting the second side 2122, wherein the angle between two intersection lines may be between 70 degrees and to 75 degrees.

The head supporting device may be designed such that a desirable position when a patient lays his head on the head supporting device may be achieved. In some embodiments, the desired position may be indicated by a desired angle between the vertical direction and a reference line within the head of the patient such as an OML or a canthomeatal line. Merely by way of example, if the desirable angle is A or between A and B, the angle between the second side 2122 and the undersurface 2126 may be (90−A) degrees or between (90−A) degrees and (90−B) degrees. An intersection line may be formed by a plane perpendicular to a length direction of the groove 2103 intersecting the undersurface 2126 and another intersection line may be formed by a plane perpendicular to the length direction of the groove 2103 intersecting the second side 2122, wherein the angle between two intersection lines may be (90−A) degrees or between (90−A) degrees and (90−B) degrees.

In some embodiments, when the patient is prone (lying on the stomach) and supports his jaw on the first surface as described elsewhere in the present disclosure, the OML may form an angle between 15 and 20 degrees with the vertical direction. In some embodiments, the patient may be supine and may support his head and neck on the continuous surface formed by the first side and the undersurface as described elsewhere in the present disclosure. In this case, as the angle between the second side 2122 and the undersurface of pad 2102 is between 70 and 75 degrees, the OML may also form an angle between 15 and 20 degrees with the vertical.

Refer again to FIG. 13 a and FIG. 13 b , the frame 2101 may also include two step surfaces 2111 in a length direction of the groove 2103. Each step surface 2111 may be located on one side of the groove 2103. In some embodiments, the step surfaces 2111 may be a continuous surface including at least a lower surface and a higher surface. The lower surface and the higher surface may be connected by a curved transition surface. Accordingly, when a patient lays his head pronely or supinely on the head supporting device, his shoulders may lie on the lower surface and contact the transition surface so that the patient may be positioned as needed in an examination.

FIG. 14 illustrates a side view of the pad 2102 of the head supporting device. The first side 2121, the second side 2122 and the undersurface 2126 may form a triangle (or quasi-triangle) in the side view. As shown in FIG. 14 , the angle between the first side 2121 and the second side 2122 may be between 20 and 60 degrees. To be illustrative, an intersection line may be formed by a plane perpendicular to a length direction of the groove 2103 intersecting the first side 2121 and another intersection line may be formed by a plane perpendicular to the length direction of the groove 2103 intersecting the second side 2122, wherein the angle between two intersection lines may be between 20 and 60 degrees. Accordingly, the center of gravity of the pad 2102 may be within the triangle formed by first side 2121, the second side 2122 and the undersurface 2126, during both prone scan and supine scan so that the pad 2102 may provide sufficient support for patient during both scans.

In some embodiments, the angle between the first side 2121 and the second side 2122 may be configured to be 30 degrees and the angle between the second side 2122 and the undersurface 2126 may be configured to be 70 degrees, so that the undersurface 2126 may form an angle of 20 degrees with the plane perpendicular to the base of the triangular shape as shown in FIG. 14 . Therefore, the OML may form a fixed angle of 20 degrees with the vertical.

FIG. 15 illustrates a front view of the frame 2101 of the head supporting device described in FIG. 13 a and FIG. 13 b . As shown in FIG. 15 , the frame 2101 may include an outer bottom surface 2112. The outer bottom surface 2112 may have a particular shape and a bed or a table (not shown in the figure) which supports the patient in examination may be configured to match the shape of the outer bottom surface 2112 so that the bed may be connected to the outer bottom surface 2112. Refer to FIG. 13 a and FIG. 15 , the length direction of the groove 2103 of the frame 2101 may be consistent with the length direction of the bed. In some embodiments, the bottom surface 2112 may be arc-shaped, while the bed may have an arc-shaped groove to match at least the length or the width of the frame 2101. In some embodiments, the bed may be designed to include a plurality of grooves with different shapes so that different head supporting devices may be implanted and used in examination.

In some embodiments, the groove of the bed may be designed that the outer bottom surface 2112 of the frame 2101 may be able to move in the length direction of the bed. In some embodiments, an electric motor may be used to drive the frame 2101 of the head supporting device in the length direction of the bed so that the patient may be positioned as needed in the examination.

In some embodiments, refer to FIG. 13 a and FIG. 15 , the pad 2102 may include a third side 2123 and a fourth side 2124. The third side 2123 may meet the first surface 2125 and the undersurface 2126. The fourth side 2124 may meet the first surface 2125 and the undersurface 2126. In some embodiments, the third side 2123 and the fourth side 2124 may be opposite to each other. In some embodiments, the third side 2123 and the fourth side 2124 may be arranged in a direction perpendicular to the length direction of the groove 2103 in the horizontal plane.

In some embodiments, two side surfaces 2132 with a particular shape may be arranged at each side of the groove 2103. In some embodiments, the side surfaces 2132 may each contact the third side 2123 and the fourth side 2124 respectively. The pad 2102 may be able to move in the length direction of the groove 2103.

In some embodiments, the undersurface 2126 and the second side 2122 of the pad 2102 may match the shape of the inner bottom surface 2131. The third side 2123 and the fourth side 2124 may match the shape of the side surfaces 2132. Accordingly, the pad 2102 may be able to move in the length direction of the groove 2103 in both supine and prone scan. In some embodiments, the inner bottom surface 2131 and the outer bottom surface 2112 may be arc-shaped.

In some embodiments, the head supporting device may be made of a shape-memory material, i.e. a material which may maintain its shape when formed and may return to its pre-formed shape under special treatment such as heating. More specifically, a head supporting device which is made of the shape-memory material may be configured to the shape and structure as needed in an examination and be reshaped to the shape and structure as needed in another examination.

In some embodiments, an electrical shape-memory system may be implanted into the head supporting device of the present disclosure. The electrical shape-memory system may include a memory and a shape recovery circuit. The memory may store different shapes and structures as needed in different examinations. The shape recovery circuit may be used to change the head supporting device to any stored shapes or structures when a specific examination is implemented. In some embodiments, a cloud-based server may be implanted to the electrical shape-memory system so that when a patient takes the scan, the settings of the structures and shapes of the head supporting device may be stored in the cloud-based server. The head supporting device may be configured according to these stored settings when the patient once again takes the scan.

In some embodiments, a pre-examination check may be implemented before the examination. The check may include a step of monitoring the size and shape of the head of the patient. In some embodiments, the check may include touching the surface of the patient's head by hands. In some embodiments, the check may include graphical method of monitoring the size and shape of the head, wherein the graphical method may include but not limit to the use of one or more video cameras, the use of light emitters and sensors, etc.

In some embodiments, the patient may be classified into a plurality of groups based on an overall or a part of his body figure. In some embodiments, the patient may be grouped by the size and shape of his head, and the structure of head supporting device may be designed to specifically suit one or more of the groups. When the patient from that or those groups lays his head on the head supporting device, he may be positioned as needed by the examination.

This description is intended to be illustrative, and not to limit the scope of the claims. Many alternatives, modifications, and variations will be apparent to those skilled in the art.
